This type of mixer is designed in such a way that the vessel imparts movement to the material of mixing by tilting the powder until the angle of surface exceeds the angle of repose. Thus powder bulk or particles slide and get mixed in the vessel. It rotates on central shaft. Shape of cylinder comes in two truncated cones joined together by cylinder section. A tight closing lid of the fast closing type for feeding material and a discharge butterfly valve at the other end of the unit which also renders a perfect tightness. Baffles are provided in bigger unit for intense mixing.
During the process of mixing particles of powder of mixing particles of powder hit each other and wall of the mixer resulting mixing action. However speed of mixture is very important. It should run at critical speed. Too high or too low speed will definitely affect the mixing process. The blender is recommended preferably when the products to be mixed have a similar density and particular size as well as no lumping properties. Over loading of mixer with powder material should be avoided. There should be sufficient room for powder to move in drum. Critical time for mixing can be set by withdrawing the samples from mixer at interval of time and analyzing it for homogenicity.
This blender is especially designed for sensitive mixtures with risk of breakage where the generation of dusts is to be avoided. The main body of the blender consists of two cone-shaped sections welded at their bases to a central cylindrical section. The axis of rotation is perpendicular to the cone axis and passes through the cylindrical section. The driving motor is located at one of the two lateral supports holding the blender body.
The solids are introduced into the blender through the loading aperture. In this type of blender, mixing takes place axially, as a result of the powder moving through the different sections. Mixing is thorough but it depends on the rotating speed

Incorporated with most advanced techniques, the Double Cone Blenders are superlative for mixing dry powder and granules homogeneously The blender is highly preferable in a number of industrial blending applications due to its easy functioning, cleaning, discharging and contamination absence. These blenders are designed in slant double cone design by making use of optimum grade materials and sophisticated techniques to make sure excellent dead spot elimination. It is integrated with no moving blades, which minimizes the particle's size reduction during blending.
Double Cone Blenders are most often used for dry blending of free flowing solids. The solids being blended in these units can vary in bulk density and in percentage of the total mixture. Materials being blended are constantly being intermixed as the Double Cone rotates. Normal cycle times are typically in the range of 10 minutes, however they can be less depending on the difficulty of blending.
